Sending Variables through remote event not working?

I have a LocalScript in a tool; heres the code

player = game.Players.LocalPlayer
mouse = player:GetMouse()

script.Parent.Activated:Connect(function()
	game.ReplicatedStorage.BallistaFired:FireServer(player, mouse)
	print(player)
	print(mouse)
end)

and heres a script inside the same tool that responds to the FireServer

game.ReplicatedStorage.BallistaFired.OnServerEvent:Connect(function(player, mouse)
	wait(.25)
	print(player)
	print(mouse)
end)

Even though each script is told to print the same variables, they come out with different outputs. The LocalScript prints "Instance" for the "print(mouse)" while the script prints "ewdoggypoopoo"(my username) for the output. Why is this? And how could I get a Players Mouse to a server script?

This is a very common problem and I recommend you try searching for an answer before having to ask here.

The Mouse object is absent on the server, so it (the server) cannot index or receive the instance. To access the values from the mouse, you must use RemoteEvents and/or RemoteFunctions and pass the required values while using the remote.

You are trying to send a reference to a local object, but since the object doesn't exist on the server, the server receives nil.

The correct method is to send whatever information the server needs from the mouse from the client

Example:

-- LocalScript
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local remote = game.ReplicatedStorage.MyRemote

remote:FireServer(mouse.Target)


-- ServerScript
local remote = game.ReplicatedStorage.MyRemote

remote.OnServerEvent:Connect(function(player, target)
    print(player.Name.."'s mouse is pointing at".. target or "the sky")
end)
